I have an older gas oven and just recently a little after we turn on the oven to bake something in it--it makes this really large bang sound, almost like something heavy has fallen over (which is what I thought it was the first time it did that, but then we realized the other night that the noise came from our oven). It only does is ever so often, but so far it hads made the noise three times when we have it on bake. I am worried there is some sort of gas issue.

Re: Oven Makes large bang sound when on
Check the floor pan in the oven. It may not be installed correctly. There may be some other parts in a bind. Some part in the oven is warped and is changing shape when the oven heats up. This would take some physical looking into.

It does sound like the bake element is probably the problem. Many ovens turn on the broil element with 120 volts to even out the heat in the oven or pulse the broil element. This may be why the oven is warm but not baking.
It sounds like the element/s have blown, especially if the fan is still working o/k.
You cannot always tell by looking at them if they are faulty or not.
Only way to be sure is to test them with a meter.
Hope this helps.

HI. an F-2 during a baking cycle is the result of an out of control oven temp that has reached Temperatures above 615F-630F
If this actual over temperature condition occurred, Look for welded relay contacts on bake or broil relays. If this happens, replace oven control (also called clock or ERC).
If no over temperature condition occurred, Look for a high resistance connection or any other cause of high resistance in the oven temperature sensor circuit. Check sensor, sensor harness and sensor harness connection at sensor and oven control. Replace sensor if found defective.
Remember: Oven control (ERC) measures resistance of sensor circuit , not actual oven temperature.
make sure that the clock is displaying the current time of day
select timed bake
select the temp of the oven you wish to bake at
set the time you wish the oven to come on with the start knob
set the time you wich the oven to turn off with the stop knob
Check the voltage on the 2 wires going to the oven gas valve. If you get 120v when the ignitor is on with no gas coming out, you have a bad gas valve. If you get voltage, but it is not much, it is the ignitor. The ignitors don't burn out completely on the ovens, they just get a little dim and no longer ignite the gas and eventually will not turn on the gas valve
If this is an older oven, check to see if it has a control knob or switch labeled "manual and "hold". Make sure it's set for manual. The hold setting maintains temp at about 140 degrees. If not the case, is this gas or electric?
